1. One of the critical roles of a fitness instructor is technique. Not being able to correct it is a hazard.

2. There's no clear value for a fitness instructor. Selling phone workouts for $0.99 in the app store is unlikely to be as profitable as 20 regular clients paying $50/week for personal attention.

Ultimately, fitness instructors provide personal services. A few outliers, e.g. Richard Simmons, can brand and sell in bulk as celebrities. But most have to focus on client relations and high touch sales.

Good luck.

Interesting. Perhaps the focus should there by be on the service and not merely the content. Good feedback - thanks.

I suggest talking to prospective users rather than people whose larger passions include typing text into boxes. No matter how much I project my mental model of my sister and brother-in-law [they are into the physical culture] into my response, it's just my mental model.
